FLY-SCREEN.

Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed August 16,1913. Serial No. 785,083.

To all whom it may concern Be it known that I, WILLIAM STOLLEY, a citizen of the United States, residing] at Vivian, in the county of Lyman andState of South Dakota, have invented certain new and useful Improvements in F ly-Screens, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to screens and more particularly to that class of screens that provide exit means for flies.

The object of this invention; is to provide such a screen that is so formed that the wire mesh is positioned to guide the flies Fig. 2 is a section taken on line 2-2 of Fig.1

1. Fig.3 is an endview of the device. Fig.

41 is atop planview of the improved screen. Fig. 5 is a section taken on line 55 of Fig; 1. Fig. 6 is a perspective view of the fly exit bar. 7 is a perspective view of a portion of the wire mesh showlng the exit aperture formed therein. Flg. 8 1s a fragmentary plan view of the blank from which the fly exit bar is formed when made of sheet metal. Fig. 9 is a fragmentary perspective view of one end of the fly exit bar when formed from sheet metal. FignlO is a section taken on line 10-10 of Fig. 9.

Referringto the parts by reference numerals, 10 denotes a frame provided with an upper :opening 11 and a lower opening 12. side edges of the openings 11 and 12 are substantially V-shaped brackets 13 that support the fly exit bar 14 by having its outer face engaging the lower face 15 of said fly exit bar. This fly exit. bar is also secured to the frame by nails or other means, as shown at 16.

Formed on the outer face of the member 14 are upwardly tapering passageways that Secured to the frame 10 adjacent the.

guide the flies to theopenings 18 at the upper end of the tapered passageways 17, this bar 14 also has a tapered or beveled face 19, the purpose of which will be hereinafter set forth.

Mounted on the frame and on the substantially V-shaped spacing brackets 13 is a wire mesh 20 which is securely held to the frame and spacing members by the securing strips 21 that areprovided with the securing means 22. These securing strips 22 rest in the cut-out ends 23 of the bar 14:. The wire mesh is held tightly between the frame and the V-shaped spacing bar, fly exit bar, and the securing strips 2]. and is also brought over and under the securing strips .14, as shown. in Figs. 1. and 2, so as to draw the mesh tightly over the openings 11 and 12. The upper strips21 are provided withibeveled faces 24L that fit snugly in the pocket formed by the beveled face 19 of the lower bar 14 and by this construction the upper securing strips arenot only held securely but the mesh covering both the upper and lower openings is substantially held upon the frame. As shown in Figs. 8, 9, and 10, the fly exit bar canbe formed from a single blank sheet :of material which blank comprises a body 25 with laterally extending cars 26 on both ends, said cars 26 provided with a beveled edge 27 and a cut-out portion 28. The body 25 also carries on one edge aseries of substantially V-shaped members 29, said members having flaps 30 that are adapted to be folded so as to form the passageway 17.

Itwill be seen from the foregoing description that inasmuch as the wire meshis pro vided with the apertures 31 that are adapted to be positioned over the openings. 18 at the top of the passage 1.7,that the flies will be guided by the slant of the wire mesh caused by the substantially V-shaped spacing bracketsinto the passage 17 and through the alined openings 18 and 31.

It is obvious that minor changes may be made in the form and construction of this invention without departingfrom the spirit thereof. It is therefore not wished to confine the invention to the exact form herein shown and described, but it is wishedto include all such as properly come withinthe scope claimed.

hat is claimed, ;is:

A screen comprising a frame provided With an upper and lower opening, substantially V-shaped spacing bloc-ks adjacent the side edges of said openings in said frame,

fly exit barsadjacent the upper edges of'said openings, Wire mesh over said spacing blocks and said fly eXit bars covering said openings,

said Wire mesh having, openings adjacent, sald fiy exlt bars, strips positioned on said frame and said spacing blocks, said upper strips having their 10Wer ends fitting be 10 neat-h the upper tapered face of said lower fly exit bar. y

In testimony whereof I hereunto affix my signature in presence of two Witnesses.
